Abstract: An electronic timepiece has a reception unit that receives satellite signals; a power supply including a battery; a remaining battery capacity detector that detects the remaining battery capacity of the power supply; an interface member; a timekeeping reception controller; and a positioning reception controller. If the user performs a positioning reception operation, the positioning reception controller does not execute a positioning reception process if the remaining battery capacity is less than a first threshold. If the timekeeping reception operation is performed, the timekeeping reception controller executes a timekeeping reception process if the remaining battery capacity is less than the first threshold.

Abstract: A ring antenna has a C-shaped loop element formed on the upper surface of a main body part including a ring-shaped dielectric material having a square cross-sectional shape. A cut part is formed in a portion of this C-shaped loop element, which is formed in the shape of a loop. In addition, an arc-shaped radiation element is formed on the inner circumferential surface of the main body part so as to be concentric with the C-shaped loop element, with a prescribed interval therebetween. The C-shaped loop element is excited by the radiation element. The tip of a feed conductor is connected to a feed part that is connected to one end of the radiation element formed on the lower surface of main body part, and electrical power is fed to the radiation element from the feed conductor.
